There is a switch available at auto parts stores that will fit right in an existing blank spot on the dash, at least in my 2012. There is an article in the honda cr-v forum that describes the switch and how to hook it up with an "add-on" fuse. Ah, found an article. Try http://www.crvownersclub.com/forums/26-racks-hitches-towing/51441-towing-crv-build-switch-pull-fuse.html. That's not the one I followed. Still looking ... Another discussion http://www.crvownersclub.com/forums/27-miscellaneous-general-cr-v-discussions/18011-towing-my-cr-v-flat-question-about-fuse-removal.html ....

I'm late to this party and you may already have done something, but the Larsen thru-glass works find. I mounted mine on the highest glass window (single pane, light tint) to the driver-side side window. Tip of antenna is lower than my highest point on the coach. I hit repeaters at 10+ miles and the APRS side of my Yaesu FTM-350, on 10W, tracked me quite nicely from Texas to Arizona (Rawhide) and back.

Great info Herman. It served me well when I got to the Rally in the Valley. I had no great surprises other than the view of 2600 coaches from the roof of my Georgetown! I attended the RV Basics course and made a lot of the additional seminar offerings. My ham radio experiment with a vertical antenna attached to the ladder, complete with the "Guilford Courthouse" flag (revolutionary war battle) flying on top was a success as well. What you included in your info was a lot of what is covered in the first-timers packet that eventually came by mail and I've suggested to FMCA that the info be sent out by email as soon as a newbie registers so that those preliminary questions get covered in a timely way. Thanks again for sharing all of that.

Great info Herman. Very helpful. Couple of additional questions -- and I realize that some may be answered in my not-yet-here packet :
Home many coaches are expected? Just curious.
Is there a reason to pull the TOAD for such as touring the area? I won't need it any time enroute and it sounds as if things are pretty busy right at the rally.
If attending the RV Basics, when do I need to be at the rally site? Not finding that sort of info except that registration for that gives 2 additional nights camping.
I assume there are many food venues available. Correct?
I've heard about getting an all-wheel weighing. When/how does that happen?
How advisable is it to sign up for electrical hookup? Why would you do that if you have an onboard generator?

It may be a java problem if you are still having trouble. You may need to update java on your computer, and if recently updated, you must reboot the computer after the update. Discovered all of that this morning.

Well, that would help wouldn't it? It's a 2016 Forest River Georgetown 378 XL. I think I've convinced myself they're working after putting a remote thermometer in the bay and observing it. The switch for the Arctic Pak doesn't tell you the pads are actually drawing current.
